Study: Common Weedkiller Turns Male Frogs into Females
------------------------------------------------------



And in science news, a new study shows one of the world’s most commonly
used weedkillers can turn male frogs into females. The chemicals in the
weedkiller atrazine disrupt development and make frogs develop both male
and female features. The European Union banned atrazine in 2004, but the
weedkiller is still widely used in agriculture here in the United
States. Researchers said approximately 80 million pounds of atrazine are
applied annually in the United States alone. Atrazine is now the most
common pesticide contaminant of ground and surface water.
